我市常年种植蔺草约0.9万公顷,有的年份超过1.1万公顷,1998年我区实际种植667公顷,占总面积的8%。由于蔺草收割早,实行机械插秧比连作晚稻容易。但机插稻根系浅易倒伏,并对秧苗高度要求严,适宜的品种较少。1997年曾用宁67机插,但因倒伏和抗病原因而产量不理想。1998年我们用甬粳18作机插品种,获得大面积成功。甬粳18茎秆粗壮,根系发达,抗倒性强,克服了机插稻根系分布浅,后期易倒伏的弱点。同时利用机插宽窄行(10厘米×23厘米)栽培的特点,充分促进其大穗优势的发挥,实现了适穗、增粒、增重夺取高产的目的。慈城镇山东村蔺草田晚稻连 About 9,000 hectares of perennials are planted in our city, some 11,000 hectares in some years. In 1998, 667 hectares were actually planted in our area, accounting for 8% of the total area. As Rush Harvest early, the implementation of mechanical transplanting than late rice easier. But the machine-inserted rice easy to lodging, and strict requirements on the height of seedlings, less suitable varieties. In 1997, the machine was used rather than 67, but the yield was not satisfactory due to the reasons of lodging and resistance. In 1998, we used Ningbo-18 as a machine-inserted variety and achieved a large area success. Ningbo japonica 18 stem sturdy, developed root system, strong lodging resistance, to overcome the mechanical distribution of rice roots shallow, vulnerable to the late lodging. At the same time, using the characteristics of machine width narrow row (10 cm × 23 cm) cultivation, fully promote the advantages of its big spike, to achieve the purpose of panicle, grain, weight gain high yield.
